in Edition Clear Qur'an by Talal Itani / At-Tawba (The Repentance)

9:42Had the gain been immediate, and the journey shorter, they would have followed you; but the distance seemed too long for them. Still they swear by God: “Had we been able, we would have marched out with you.” They damn their own souls, and God knows that they are lying.

9:56They swear by God that they are of you. But they are not of you. They are divisive people.

9:62They swear to you by God to please you. But it is more proper for them to please God and His Messenger, if they are believers.

9:74They swear by God that they said nothing; but they did utter the word of blasphemy, and they renounced faith after their submission. And they plotted what they could not attain. They were resentful only because God and His Messenger have enriched them out of His grace. If they repent, it would be best for them; but if they turn away, God will afflict them with a painful punishment—in this life and in the Hereafter—and they will have on earth no protector and no savior.

9:95They will swear to you by God, when you return to them, that you may leave them alone. So leave them alone. They are a disgrace, and their destiny is Hell; a reward for what they used to earn.

9:96They will swear to you that you may accept them. But even if you accept them, God does not accept the wicked people.

9:107Then there are those who establish a mosque to cause harm, and disbelief, and disunity among the believers, and as an outpost for those who fight God and His Messenger. They will swear: “Our intentions are nothing but good.” But God bears witness that they are liars.
